GUIDE-BOX.

SPECIFICATION forming part of Letters Patent No. 404,178, dated May 28, 1889. Application filed February '7., 1889. Serial No. 299,033- (No model.)

To all whom it may concern:

Beit known that I, PATRICK L. DAY, acitizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and `useful Improvements in Guide-Boxes, of which the following is a specification, the principle of,

the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

I'Ieretofore in boxes for entranceguides for rod-rollingmills the guides have beensecured in place by means of set screws or bolts threaded through the box at the top and sides. To regulate thelocation of the opening in the guide and cause it to register exactly with the desired rolling-grooves in the rolls, two set-screws have usually been employed on each side of the guide-box, the first screw in each set located near the inner end of the guide, the second screw in the set located near the outer end of the same. These set-screws have been provided with atransverse hole or opening in their heads, in Which a pokerwrench could be inserted vto tighten up the screw and adjust the location of the guide. To prevent the loosening of said set-screws by the continuous jarring of the rolls, pins are inserted in the openings in the heads of the set-screws. When it is desired to take up the slack caused by the wearing of the guides orto adjust horizontally the guides, so that their openings will register exactly with the desired groove of the rolls, the pins are drawn out and the set-screws farthest removed from the rolls, which I designate as the outer pins, are without trouble regulated by' means of a poker-Wrench. WVhen, however, it is desired to regulate the inner setscrews that are nearest the rolls and by which the inner ends of the guides are adjusted, great difficulty is experienced for several reasons-first, the space between the adjacent guide-boxes is so small that little room is afforded for operating therein; second, owing to the water that is continually running on the rolls steam is constantly arising th ere from, obscuring the sight of the rolls and rendering the ditiiculty of finding the opening in which to insert the poker-wrench doubly tryhead of the operative parts near the outer end of the guide-box, Where there is room for adjusting the same and no liability of the .parts being obscured by the issuance of the steam from the rolls.

Referring to the drawings, Figure l is a perspective view of my improved guide-box in conjunction with a stand of rolls, certain parts of the latter being sectioned away. Fig. 2 is a plan view of a portion of the guidebox, showing the guides in position, the box having its inner end raised until the barrels in which the adj usting-bolts fit are in a horizontal plane. Fig. 3 is ahorizontal section of my modified form of adjusting device.

Ais the guide-box, of usual form as to most of its features, and provided with the horizontal opening a., in which fit the guides a. Set-screws b, threaded through the top of the box, secure said guides in vertical position, and set-screws b', threaded through the re'- spective opposite sides of the box, secure the outer extremities of the guides in horizontal adjustment.

Pins c, of rectangular body form in crosssection, fit in suitable openings near the inner ends, c, of the respective sides of the guide-box, the ends of said pins engaging with the inner ends of said guides and holding them in horizontal adjustment. The outer extremities of said pins are formed, respectively, with angular heads d of greater transverse area than the pin itself, thus forming the shoulder d', that serves to prevent the pin dropping through the opening in Which it fits when the guides are removed. Barrels e are cast on the respective opposite sides of said guide-box at adownward inclination from the outer to the inner end. Said barrels are counterbored for a portion of their length and IOO tapped out the remaining portion, andin said tappedout portion are respectively threaded the bolts j', provided with the angular ends f, that engage closely with the angular heads rl of the respective pins c. The heads g of said bolts may be of any form suitable for turning by wrench or tongs, and are located near tho outer end ot the guide-holding portion of the box, in order that they may be easy ol. access and conveniently located for the operator to turn and adjust easily and expeditiously.

Fig. 2.3 represei'lts a modiiication of my device. ln this li'orm a recess, 71., is provided in each otl the two opposite side walls of the guide-box, and I provide the said recesses thus l'ormed respectively with the angular shoulders 7a.. The outer end of the box is also provided on each side with an angular shoulder, h2, said shoulders 7i. and 7b2 having the same degree of slant or angularity relative to the outer side of the bo;\. .lhe said outer opposite sides oi the box in this modi- .lied lorm are cast smootlrsided without the barrels c.

Slides l( are provided attheir forward and rear portions, respectively, with the angular shoulders 7.', of equal slant and angularityrelative to the smooth-faced inner side, 7s', oi? the slides. Near their outer ends said slides are respectively.provided with slots 7a2, of suilicient size so that bolts l may have easy lon gitudinal movement therein, and said slides may move transversely of the bolt. Side walls, a, oi? the box are tapped out lr'mgitudinally, and said bolts l are respectively threaded therein, the inner extremity of said bolts respcctively engaging with shoulders Z', ormed on the Vinner portion of said slides.

The (.)peration ot' the preferred :form is readily lnulerstmnl, and Vis as Afollows: \Vhen it its desired to adjust the guides, the bolts are turned up, and as their angular ends engage with the angular heads of the pins the latter are `lorcml. inward, causing them to crowd. against the guides, by means of which the latter are adjusted. One bolt a-nd pin may be moved without the other, or one may be moved in one direction and the other may be moved in the opposite direction, according as the :uljustmentot' the guides to the rolls requires. This is also true oit the modified form. The pins are, as has been stated, made rectangular i n cross-section, and thus cannot bc turned by the jarring of the rollsiands would be the case it the pins were oli' circular cross-section.

The operation of the modification as f ollows: When it is desired to regulate or adjust the location et' the guides relative to the rolls, thebolts maybe given a turn or two inward, and this causes the slides to be lforced ['mward and :ulguhn' shouldms /r ot the slides to en (`r 1go with the shoulders 7i. 712, thus as the slides are forced forward the angularity of the respective shoulders causes the slides to be moved inward toward each other in a direction transverse to the length of the box. The guides being placed intermediate of the slides are also caused to move simultaneously and correspomlingly with the slides.

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment o'ii' my invention. Change may be made therein provided the principles of construction respectively recited in the tollowing claims are employed.

I therefore particularly point out and distinctly claim as my invention l. In a guide-box, the combination, with a guide, of adjusting mechanism engaging with the inner end of said guide and having its outer extremity located near the outer end of the guide-box, substantially as set forth.

2. In. a guidebox, the combination, with a guide, of a guide-adjuster having its inner extremity engaging with the inner end ot' said guide, the outer extremity oi' said ad juster located. near the outer extremity of said guide-box, substantially as set forth.

3. In a guide-box, the combination, with a guide and a pin engaging with it, said pin having an angular head, oi' an actuating-bolt movably iitted in said guide-box and provided with an angular extremity engaging' with the angular head ol' said pin, the head ot said actuating-bolt located near the outer end of said guide-bex, substantially as set forth.

Li. In a' guidebox, the combination, with a guide and a pin provided with an angular 'head, of a bolt threaded in said box, the head of said bolt located near the outer extremity of said guide-box, the point of said bolt ol angular formation' and engaging with `the head oi' said pin, substantially as set forth.

5. The combination of a guide-box provided with a guideopening and a pin-opening, said latter opening located near the :in ner end ot the box, a guide fitting in said first opening, a pin rectangular in cross-seetion and Yfitting in said pinopening, said pin provided with an angular head ol' greater transverse area than the body of the pin,said guide-box also provided with a barrel, and a bolt threaded in said barrel, the point ol. said bolt being angular and engaging with the head ol the pin, the head of said bolt located near the outer end ot' the guide-box, substantially as set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 4th day of l `ebruary, A. l). isst).
